Observed: 29th September 2011 By: miked

Not really sure what kind of lichen this might be


Caution: Do NOT use iSpot to identify fungi to eat!

Some fungi are very poisonous so a mistaken ID could have serious consequences.

    Likely ID
    Stereocaulon sp.
    Confidence: It's likely to be this, but I can't be certain.
Species interactions

No interactions present.

I really don't know what to make of this. Do you have a closer photograph that shows the thallus surface and apothecia in fine detail?

My impression from those parts of the photograph that are approximately in focus is that this is a foliose lichen, seemingly in the Parmeliaceae, but the apothecia lack margins and are more like those of a Stereocaulon. I have checked a couple of Scandinavian lichen books without finding anything, and it occurs to me that this is your problem, not mine, and am heading to bed! I have another, older Scandinavian lichen flora that I might look though tomorrow, but time is a big issue now.

A flight of fancy is that this may indeed be a Parmelia or Parmotrema or something similar, and that the fruiting bodies are actually a heavy infection by a parasitic Abrothallus species. Dunno. Bedtime.

Have put the full resolution

Have put the full resolution image on, not sure this shows any more detail but it might help. Only took one photo. Shame I could not take the proper close-up kit with me on the trip.

Thanks for all your help with identifications.

The 'lichen' was on the side of a carpark in a skiing area (if you zoom in on the location it takes it to the exact place within a metre or two). the place had vegetation height of a couple of cm mainly moss with a few other lichens and fungi.

Thanks, will ask some of the

Thanks, will ask some of the Russian colleagues if they know of a Siberian lichen flora, although its almost certain to be in Russian.
Interesting you mention "phyllocladia" as there is a genus of conifers called Phyllocladus with flattened structures, think I put one of these on from NZ in early stage of ispot. Its shoots look like leaves and the leaves themselves are almost non-existant.

They mentioned that Stereocaulon is likely for this observation but they are not an expert in this group.
